Clearly he means that it's shitty for people who relied on the exploit, but without monetizing it. When Beeper started monetizing it, obviously Apple had to close it, and hobbyists suffered.

As someone that knows people that use Matrix bridges, I feel confident that 99% of those people would blame Apple and not Beeper. Either the exploit is bad and Apple would have shut it down regardless, or it's benign and Apple is trying to secure their manifest destiny. The monetization aspect of it feels completely tangential when there is no sanctioned "free" route anyways.
